T0 all whom it ma z concern: I

' Be it known that I, Cannes A. BARRY,- a

citizen of the United States, residing" at Sutherland',-in the county ofOBrlen and State OifIOWit, have invented new and useful Improvements inTractor Hitches, of which thefollowing is a specification.

This invention relates to an improved hitch for connecting a tractor toan implement, such as a corn picker the general object of the inventionbeing to provide means "forattaching' the frontpart of the implement tothe tractor sothat the tongue truck can be eliminated, and the weight,formally carried by such truck, carried by the tractor. Another objectof the invention is to eliminate the side draft and. to permit thetractor to travel over that part of the field bwhichhas already beenpassed over by the implement.

A further object of the invention is to provide means whereby theimplement can be attached to different types of tractors and atractorattached to different types of f implements.

This invention alsoconsists in certain. other features of constructionand in the" combination and arrangement of the several.

parts, to be hereinafter fully described, il-

lustrated in the accompanying drawings and" specifically pointed outinthe aplike or corresponding parts throughout the of the implement. V

' carrying out my invention 1 provide a main together by a number'ofpairs of upper and formed by the'parallel portions of the beams 1i and 2and said draft bar extends at an Figure 7 isia' view of the bracket forconnecting thezhitch toapart of the implement. Figure: 81 is a view ofthe bracket which may be. used? with the hitch.

Figure 9 is a view of a support for holding the bitch in: raisedposition when detached from the tractor.

In these views, A indicatesa tractor and B a: corn picker. or otherimplement. In I beam 1 and a supportingbeam 2 which are preferably of:lifbea'm construction.

The front partsof thebeams ext'end parallel and: abut each other withthe rear parts separated and extending: at different angles 5 to thefront of the picker, thebeam' 2 being almost straight, and the rear partof the beam 1 extending upwardly at an angle. The front endsof the beamsare connected lower plates 3 and the bolts 4' which'pass throng-hi theplates and through portions of the; beams. A draw bar 5 extends into thespace formed by the. beams at the :fr'ont thereof, this draw bar beingcomposed of upper and lower pieces: 6 and the eye; pieces 71 whiclrconnect the pieces 6 together, The pieces 6 are 5 provided with eyes 8at their front ends so that the draw bar can be fastened to the draw barof the tractor by theusuah coupling. pin shown at 9 in Figure- :1. Acoupling. bolt 10 connects the rear end ofnthe draw bar to a draft bar11: which projects into the rear part of the. space 7 B5 the pin orbolt14K which forms a hinge connection between the beam and picker. Onebracket 1'3 is bolted to the top of the beam bythebolts 15' and theother bracket is "boltedto the pickerby the bolts 16 with the limbs Ohone bracket overlapping: the limbs of the other and the'vbolt '14passing through the holes in said limbs. The beam 1 is fastened to-abrace 17 of the implement by the clamps 18 and said beam is alsofastened to the short tongue 5 of the implement by the clamping plates19 and the bolts 20. Blocks 21 are placed between the tongue b and thebeam and these blocks are beveled so that the tongue can be adjustedtowards and from the beam by moving one block upon the other, thusenabling the implement to be properly adjusted and also permitting theimplement to be used with different types of tractors or a tractor withdifferent types of implements.

This adjustment is made after the clamp 18 is loosened and as thisadjustment is being made, the member 2 will move on the hinge bolt letso that it is not necessary to touch the connection between member 2 andthe implement. The front ends of the members 1 and 2 have their webs cutaway as shown in Figures 2 and 9 so as to not interfere with the turningmovement of the tractor implement by permitting th draw bar of thetractor, when the same is of considerable size, to enter the openingformed by the cut away portions. A yoke-shaped frame 22 is fastened tothe front end of the hitch by the bolt 23 which passes through the frontends of the beams and through any one of a plurality of pairs of holes24 made in the yoke to hold the front end of the hitch ofi the groundwhen the hitch is disconnected from the tractor.

I also provide the bracket 25 which may b bolted to the beams 1 and 2 bythe bolts which pass through the bracket and the holes 26' formed in thebeams, this bracket being designed to support a shaft when the picker isto be driven by power.

From the foregoing it will be seen that I have provided means forsupporting the front end of an implement from the tractor so that thefront truck of the implement can be omitted and which gives bettertraction for the tractor on account of the extra weight. This devicewill also eliminate side draft and permits the tractor to run over thatpart of the field that has been picked. By using different sizes ofblocks the device can be adjusted to suit different tractors andimplements. The draft bar and draw bar are also so arranged that theentire pulling strain is taken by. these parts and thus the beam 1 and 2and their connections are not subject to this strain.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may makechanges in the constructionand in the combination and arrangement of the several parts,- providedthat such changes fall within the scope of the appended claims.

lVhat I claim is 1. In combination with a tractor and an implement, aframe having one end supported on the tractor and its other end attachedto the implement, the rear part of the frame extending at an angle sothat the implement will not track the tractor and a draw bar and draftbar connecting the implement with the tractor and taking the entirepulling strain.

2. In combination with a tractor and an implement, a pair of beamshaving straight front parts which abut each other and angularlj;arranged rear parts, the rear part of one beam extending at a greaterangle than the other and also extending upwardly at an incline, meansfor fastening the front ends of the beams together, means for clampingthe rear ends of the beams to a part of the implement, a draw bar forsupporting the front ends of the beams from the tractor and a draft barfor connecting the draw bar with an implement.

3. In combination with a tractor and an implement, a pair of beamshaving straight front parts and angularlyarranged rear parts, the rearpart of one beam extending at a greater angle than the other beam andextending upwardly at an angle, means for clamping the ends of the beamsto a part of the implement, adjustable means for fastening the upwardlyextending part of one beam to the tongue of the implement, plates forconnecting the front ends of the beams together, a draw bar arranged inthe space between th front ends of the beams and a draft bar forconnecting the draw bar with the implement.
